It started earlier this month. Church staff at the Immaculate Heart of Mary Catholic Parish in Northglenn noticed someone had smashed their lights and tried to break into the church.
Then, on Sunday, a woman stole some items from a shed that the church distributed to the local homeless population.
On Tuesday, church staff told 9NEWS someone took two bikes from the church. The church was saving those bikes to give to underprivileged youths during the holiday season.
Staffers at the church told 9NEWS they've reported the thefts to the Northglenn Police Department. Officers are looking for them.
The church took to Facebook and posted photos of the alleged thieves - you can view the post at this link or on below.
